Abstract
An integrated circuit (100) includes functional input and output signal leads (101,111), input and output circuits (102,112) connected to the functional input and output signal leads, core circuitry (120, 122, 124), and interconnect wires and circuits (103) connecting the input and output circuits and the core circuitry. The integrated circuit further includes an addressable test port (105, 115, 135) for each core circuitry. Each test port is connected to its respective core circuitry and to the interconnect wires and circuits. External test signal leads (106) connected to each test port.
